HA Series Heavy Duty Connector, 4+PE, Screw Terminal, Side Bulkhead, Top/Side Entry, 10A/250V
Introduction:
Heavy-duty connectors (HDC) use strong aluminum or thermoplastic housings to protect against dust, moisture and mechanical stress. They consist of five main components: housing, hood, inserts, contacts and cable glands. Modular and monolithic inserts combine power, signal, data and pneumatic lines in one connector to save space in control cabinets. Flexible cable outlet directions and hoods for large-diameter cables also help with wiring in tight spaces.
The HA series heavy duty connector delivers a dependable 4+PE connection solution for compact control systems. Rated at 10A and 250V, this assembly is equipped with a side-bulkhead base, enabling secure attachment to equipment walls or panels. The kit prioritizes user convenience by featuring inserts with screw terminal technology, which facilitates quick assembly using standard screwdrivers without crimping tools. Paired with a hood capable of either top or side cable entry, this rugged connector ensures optimal protection and mechanical stability for industrial machinery.
Note: The product supports multiple thread size options, and customers can choose the specification that matches their installation needs.
